Industries and governments had a really weird preoccupation with protecting people from margarine way before it was made with the hydrogenated oils that led to its unhealthy reputation in more recent years. There's even bootlegging involved.

Until 1975, children with disabilities in the U.S. weren't guaranteed the right to a public education. The ruling in Brown v. Board sparked a series of cases related to children who had been segregated or restricted from schools based on disabilities.

It would be next to impossible to have ever had a class on American history or the American Civil Rights Movement and not heard about Brown v. Board. But the case is much more complicated than just one child in one segregated school system.

The ruling in this infamous U.S. Supreme Court case stated that segregation was legal as long as the separate facilities were equal. But most people are more familiar with the name of the case than with the actual events that transpired around it.
